An echo is returned in 6 seconds. What is the distance of reflecting surface? from source? [Given that speed of sound is 342 m/s.] |

Answer» GIVEN.. TIME in which echo RETURNED t=6s. speed of sound v=342m/s. distance=speed*time=342*6=2052m. As this distance is twice the distance of reflecting SURFACE from source. so, the distance of REFLECT surface=2052/2=1026m |
